CVE-2025-38592

CVE-2025-38592 affects the Linux kernel Bluetooth subsystem. The issue arises in hci_devcd_dump where dev_coredumpv and skb_put_data both use hdev->dump.head, allowing a freed vmalloc buffer to be accessed and causing vmalloc-out-of-bounds access. The documented root cause is that dev_coredump...

CVE-2025-38591

CVE-2025-38591 affects the Linux kernel and is resolved by a patch in the BPF verifier. The issue involved a narrowing context access check in BPF, where a program attempted to read a pointer field (offset 169) in __sk_buff (field sk at offset 168). The verifier incorrectly allowed this “narrower...
